Since the choices is from 0000 to 9999, therefore there
are a total of 10,000 possibilities.
The possibilities that the number begins with a 3 and ends
in a 2 or 0 is:
possibilities = 1 * 10 * 10 * 1 + 1 * 10 * 10 * 1 = 200
Therefore the probability is:
P = 200 / 10,000 = 0.02 = 2%
So there is a 2% probability.
